AUTOMATIC ANNUNCIATOR.

Specification of Letters Patent.

Patented illy 20, 1915.

' Application filed May 14, 1913. Serial No. 767,563.

The object ofthe invention is to provide .a new and improved annunciatorarranged to display the time of the day or night on a distant surfacetogether with any desired legend or other subject matter, such as ad'vertisements, titles of vaudeville acts or of moving pictures, etc.

In order to accomplish the desired result use is made of a projectingapparatus provided with a revoluble slide carrier on which a series ofslides are mounted, and of which slides each is adapted to pass into thefield of the'appa'ratus on intermittently rotating the slide carrier,and a time-indient ing device arranged in the field of the apparatus andwholly independent of the slide carrier and its.- slides so that boththe subject matter of a slide and the time-indicating device aresimultaneously. projected onto a distant surface.

A practical embodiment of the invention isA represented in theaccompanying drawings forming a part of this specification, in

. which similar' characters of reference indicate corresponding parts inall the views.

Figure 1 is a sectional side elevation of the annunciator on the linel-l'of Fig. 2; Fig. 2 is a sectional plan view of the same on the line2-2 of Fig. l; Fig. 3 is a cross section of the same on the line 3*?) ofFig. 1; Fig. '4; is an enlarged sectional side eleva tion of thetime-indicating device; Fig. 5 is a face view of the minute hand disk;Fig. 6 is a similar View of the hour hand disk; Fig. -7 is a face Viewof one of the slides; Fig. 8 is' an enlarged side elevation of theactuating mechanism for the slide carrier, parts being in section; Fig.9 is an enlarged face view of a modied form of the time-indicatingdevice; and Fig. l0 is a sectional side elevation of the sa-me on theline 10-10 of Fig. 9 and shown in connection With/)the slide carrier.

In carrying out the invention use is made of aprojecting apparatus Ahaving a casing A in which is mounted an objective B, a condenser lens Cand a source of light D in the rear of the condenser lens, as indi#cated in ,Figs l and 2. The casing A is removably held on a bracket Eattached to awall, post or other suitable support and having a rod Epassing through an apertured boss A2 held in the bottom of the caslng A.The boss A2 is provided with a set screw E2 adapted to engage the rod Eso as to securely fasten the casing A on the rod E of the bracket E.

IVithin the casing A of the projecting apparatus A is mounted to rotateintermittently aslide carrier F, preferablv in the form of a. skeletonwheel provided at its peripheral face with guideways F for the receptionof removable slides (Jr containing the subject matter to be projected'by the projecting apparatus onto a distant screen, wall, sidewalk orother surface. By reference to Figs. 1 and 2 it will be noticed that thecondenser lens C and the smirce of light D are arrangedv within theslidecarrier F in such a manner that the slides G move successively.into thefield of the projecting apparatus, that i s, between thecondenser lens C and the objective B.

The slide carrier F is rotated intermittently at the option of theoperator in charge so as to -permit of displaying the subject matter ofthe slide G, in active position at the time, any desired length of time,and for this purposethe'following arrangement is made: Theslide carrierF is provided with a hub F2 mounted to rotate loosely on a shaft Hattached to the door or cover A3 on one side of the casing A, and on thesaid hub F2`is secured a gear wheel I (see Figs. 2 and 8) in .mesh witha gear wheel I secured on a transversely-'extending shaft I2 journaledin suitable bearings arranged on a bracket A4 attached to or formingpart of the door A3. On the shaft I2 is secured a toothed wheel Jengaged by an escapement lever J fulcrumed at J 2 on the bracket A4.rI`he escapement lever J is provided with an arm J 3 extending betweentwo pins K held on an armature lever K ulcrumed loosely 'on the shaftI2. The armature lever K is 1adaptedto be swung downward by the actinofa pair of electro-magnets L when' the latter are energized, and a Ispring K2 connected with the free end of the armature` lever K serves toswing the armaturelev'er K upward whenever the electromagnets L aredenergized. The electromagnets L are in an electric circuit' L -providedwith a battery or other source of electrical energy, L2 and with aswitch VL3 under the control of an operator at any desired distantpoint. When the switch L3 is closed the electro-magnets L are energizedto swing the lever K downward,

l and whenv the switch is opened the electromagnets L are denergized toallow the sprinor K2 to swing the armature lever upward. On the armaturelever K is fulcrumed a pawl K2 adapted to engage the .teeth of the wheelJ, and the said pawl K3 is pressed on by a spring K4 attached'to thelever K to. hold the pawl in engagement with the Wheel J. Y Now when thearmature lever K lisfswung downward the pawl K3 glides over the teeth ofthe wheel J and at the same time the armature lever K actuates theescapement lever TJ "by the pin K so as to release thev Wheel J, andwhen the lever K- swing'supward the pawl K3 turns the wheel J until theescapement lever J again locks the 'wheel J against further rotation. It

,will be noticed that when the .wheel J srotated in 'thedir'ection ofthe arrow a then a rotary motion is given by the gear wheels and I totheslide carrier F so that the next following slide G is moved into thefield of.

is the same, practically, as that disclosed in my Patents No. 1,097,310,granted May 19, 1914, rand No. 1,101,429, granted June 23, 1914.

A time-indicating device N extends into the field ofthe projectingapparatus A in front of the slide G in active position at the time, and`this time-indicating device is so arranged thatthe correct time of thedayv or night is projected onto the distant surface together with the-subject matter of the ac tive slide G. The time-indicating device Nconsists essentially of a dial N, an hour disk N2 and a\minute` disk N3the disks being made of glass, mica or other suitable transparentmaterial. The dial N is attached to a framework- O secured to anddepending from the casing of a timepiece P, such as a clock or watch ofany .approved construction, removably mounted within the casing A by aset screw P", as plainly indicated in Fig. 1. The dial N is providedwith the lusual graduation and numerals indicating hours and minutes,similar to those of any clock or 'watch (see Fig. 3), and the disk N2-the timepiece P and for this purpose the hour and minute arbors of thetime-piece are provided with gear wheels Q, Q (see Fig. 4) in mesh withintermediate gear wheels Q2, Q3 journaled on the frame O and in meshwith gear wheels N", N7 carrying the transparent disks N2, N3. The wheelN7 is provided with a hub- N8 mounted to turn in the frame O, and thewheel N6 is mounted to ,turnloosely on the hub N8. Now it will benoticed that by the arrangement described the timepiece P rotates thedisks N2, N3 so that their hands N4, N5 'indicate the correct timecn thegraduation and numerals of the dial N,-and as the said disks N2, N? andthe dial N are in the field of the projecting apl-v paratus, it isevident that the hands and the graduation `and numerals are displayed ona distant surface to indicate the correct time of the day or night.

Each of the slides G is provided with a legend G for indicating thetitle of avaudeville act or that of a moving picture or the like, andthe slide G is also provided, preferably at the sides, with panels G2for containing subject matter such as advertisements, pictures and thelike, and the space GS/between the panels G2 is in alinement with thetime-indicating device, that is, with the dial N and the disks N2, N3 sothat the time appears on the distant surface at the middle of theScreen. It is understood that I do not limit myself to the specialarrangement of the slideG as described, as the same may be varied tosuit existing conditions.

ln the modified form shown in Figs. 9

and 10, use is made of two concentric disks R and R of transparentmaterial, and of which the 'disk R is provided on its face withnumeralsR2 indicating the hours of the day or night, and on the disk Rare arranged the numerals R" from 2 to 60, indicating minutes. The hourand minute disks R and R are mounted to rotate loosely on a shaft R4.held on a frame 0 attached to a timepiece P2 fastened in the casing A',the same as the timepiece P previously mentioned. On the hour and minutedisks R and R are secured gear wheels S, S in mesh with intermediategear wheels S2, S mounted to rotate loosely on studs S carried by thetrame O, and gear wheels Tf1" mesh with the said intermediate gearwheels .R and R are rotated in such a manner that y
